Is there a LaseOptics Lensed Fiber that’s a perfect fit for your application? Let’s find out.

Lensed Optical fibers are used to couple light between optical fibers and laser diodes, laser chips, semiconductor optical amplifiers, waveguides, photo diodes and other devices. Optical Fiber lensing technology enables highly effective coupling efficiency within a small space and compact packaging, an advantage not offered by bulk optics alternatives. In recent years, substantial changes have occurred in lensed fiber technology to increase flexibility and extend optical performance. Two significant developments–the advancement of fiber polishing technologies and the development of novel lens designs–stand out.

Advances in polishing …
In optical communication systems, 980 nm high-power laser modules are applied for long-distance communication amplifiers. Since the mode field of the 980 nm laser diodes is different from single-mode fibers, coupling losses may occur. In order to improve this problem, lensed fibers have been used widely recently, such as lensed fiber employing conical/wedge lensed fiber end face. These can easily yield any elliptical Micro-Lens aspect ratio to match the far field of the high-power laser diode but the fiber end face must be polished and then spliced during present manufacturing process. It is a time-consuming task and the melting depth of the fiber end face is controlled with difficulty. This study develops a novel fiber end
face polishing/laser fusion method for manufacturing the lensed fiber employing. Using this new method, the coupling efficiency exceeds 80%.

The ability of getting a mode field diameter which is close to 60 µm leads to high positioning tolerance and high coupling ratio. These optical components are also available with end surface coatings such as angled polished point which allows a less than -50 dB return loss as well as high power carrying. Lensed fibers can be inserted into different types of optical connectors or ferrules. Lensed fibers developed by LaseOptics Taper Fibers constitute an excellent way to couple the lensed optical fibers and laser diodes and waveguide for example.
